Abstract OBJECTIVE: As conflicting results have been observed by some authors in liver recipients, the aim of the study was to evaluate lamivudine therapy in 3 groups of patients with chronic hepatitis B: non-transplanted patients, liver and kidney recipients. METHODS: All patients were studied for clinical symptoms, hepatic enzymes, hepatitis B virus (HBV) serology, serum HBV DNA load, and HBV polymerase genotype (mutations associated with lamivudine resistance). RESULTS: During the 48-144 week-long follow-up (mean: 75 weeks), 23 non-transplanted patients, 5 liver and 6 kidney recipients were studied. A sustained biochemical and virological response was obtained in 19 out of the 23 non-transplanted patients and in 4 of 6 kidney recipients, while the 5 liver recipients did not respond. After the development of lamivudine resistance, mutations rtM204V and rtL180M were detected in all studied patients, mutation rtM207I in one, with similar results from traditional nucleotide sequencing and a commercial line probe assay. CONCLUSION: The poor response to lamivudine in liver recipients requires further studies.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
  • Clinical Information: The study is a clinical or epidemiological study and provides basic information about the population.
  • Treatment: The study mentioned a certain treatment method, such as drug resistance caused by mutations. If the study does not specifically indicate the relationship between mutations and their correspondence treatment, the main treatment studied in the article is marked.
  • Location: The source of the research data.
